HECTOR LEDOUX, OF VVOROESTER, MASSACHUSETTS, ASSIGNOR TO OROMPTON & KNOWLES LOOM WORKS, A CORPORATION OF MAS- SAOHUSETTSJ SWlVEL-LOOIVI.

Specification of Letters Patent.

Patented Dec. 12, 1905.

To aZZ whom it may concern.-

Beitknown that I, HECTOR LEDOUX, a citi- Zen of the United States, residing at VVorcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Swivel-Looms, of which the following is a specification.

My invention relates to looms in which, in addition to the ordinary fly-shuttle, swivelshuttles are used to weave spots or figures on the fabric and the swivel-shuttle rail carrying the swivel-shuttles is supported independently of the lay and is not attached to the lay; and my invention more particularly relates to the swivel-shuttle mechanism.

' The object of my invention is to improve upon the swivel-shuttle mechanism as ordinarily made and o provide, in addition to the ordinary crank-shaft for operating the lay, a second independent crank-shaft and connections to the swivel-shuttle rail to operate said rail carrying the swivel-shuttles to cause it to moveinto aposition for. the swivel-shuttles to be carried into the shed and out of such position, and, further, to provide two sets of swivel-shuttles extending in a horizontal plane, one on the front side of the swivelshuttle rail and the other on the rear side, with the guide-eyes for the thread from the spools or bobbins carried by the'swivel-shuttles at the inner ends of the swivel-shuttles.

My invention consists in certain novel fea tures of construction of my improvements, as

will be hereinafter fully described.

I have shown in thedrawings only detached parts of a swivel-shuttle loom and swivelshuttle mechanism embodying my improvements'suflicient to enable those skilled in the.

one end of the swivel-shuttle rail and its supporting-rod looking in the direction of arrow 0, Fig. 2. The shuttle-rail at the right is broken away. Fig. 4 is a detached plan view of the swivel-shuttle rail shown in Fig. 3 looking in the direction of arrow 0Z, same figure. The supporting-arm at the end is shown in section. Fig. 5 is a cross-section on line 5 5, Fig. 3, looking in the direction of arrow 6, same figure, and showing the warp-threads and the threads from the swivel-shuttles.

In the accompanying drawings, 1 represents the loom sides or frames; 2, the breast-beam; 3, the lay-beam, supported on the upper end of the lay-swords 4 and carrying the reed 5 and hand-rail 6 and connected with the driven crank-shaft 7 through the crank-connectors 8, all in the usual way.

1 will now describe my improvements. Two longitudinally-moving rods 9, one near each end of the loom, are supported and have a reciprocating longitudinal movement in bearings 10 and 11 on brackets 10 and 11, respectively, secured to the loom-frame. A collar 12 is adju-stably secured by a bolt 12 on each rod 9 between the forked end'of the yoke 13, which has bosses 13, mounted on the rod 9. To the lower part of the yoke '13 is pivotally attached one end of a crank-connector 14:. The other end of the crank-conn'ector 14: is connected with a crank-shaft 15, mounted in suitable bearings 15 atthe rear of the loom-frame. On the forward end of each rod 9 is adjustably mounted by a bolt 16 a collar 16, which has thereon two pendent arms 17, between the lower ends of which extend the ends of the swivel-shuttle rail 18, which is secured to the arms 17 by screws 17 or otherwise. The swivel-shuttle rail 18 carries two longitudinally-moving racks 19; having engaging ends 19 on the upper side of the rail 18, which are connected with mechanism (not shown) for moving the racks in any usual and well-known way. The racks 19 mesh with and rotate pinions 20, which in turn mesh with horseshoe-gears 21, so termed, (see Fig. 3,) on which are supported the swivel-shuttles 22 to communicate a movement to said shuttles to carry them into the shed, as indicated by broken lines in Fig. 2, when the lay is in its rear position, and out again, all in the usual and well known way. Two sets of swivel-shuttles 22 are shown in the drawings, one on the front side of the swivel-shuttle rail 18 and the other on the. rear side thereof. Each swivel-shuttle 22 carries a spool 22, in the usual way on which is the thread 22 for the spot or figure to be woven on the fabric. (See Fig. 5.) Each swivel-shuttle 22 has a guideeye 22" for the thread 22", which guide-eye is located at the inner end of the swivel-shuttle 22 (see Fig. 5) instead of at the outer end,

as is customary. By this arrangement of the guide-eyes 22 for the threads 22 on the spools 22 the threads are brought or guided to the proper position over the warp-threads 23 for the figures or spots to be woven by the movement of the swivel-shuttles 22.

I have found in practice that when the. lay is in its rear position and the shed is open, as shown in Fig. 1, there is room for the operation of both sets of swivel-shuttles 22, one on the front side and the other on the rear side of the swivel-shuttle rail 18, and that with the thread guide-eyes 22 at the inner ends of the swivel-shuttles the threads 22 will be in position to properly weave the spots or figures.

I will now describe the mechanism shown in the drawings for operating the rods 9, carrying the swivel-shuttle rail 18, to cause said rods to move forward and backward and carry the swivel-shuttles into operative position, as shown by full lines in Fig. 2, or out of operative position, as shown by broken lines in said figure. On one end of the driven crank-shaft 7 is in this instance fast a gear 24, which meshes with and drives a gear 25,

obtained independently of the movement of the crank-shaft 7 from some other driven mechanism on the loom, and the timing of the movement of the crank-shaft and the rods 9, carrying the swivel-shuttle rail 18, may be determined by indications of a pattern mechanism, if desired.

The advantages of my improvements will be readily appreciated by those skilled in the art, and they may be adapted to be applied to swivel-looms of any ordinary construction.

It will be understood that the details of construction of my improvements may be varied, if desired, and that the independent crank-shaft for the swivel-shuttle rail may be used with any ordinary construction of the swivel-shuttle rail and swivel-shuttles without regard to whether the shuttles extend in a horizontal plane or a vertical plane.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a loom of the class described, a lay, a crank-shaft for operating the lay, a swivelshuttle rail and a second crank-shaft for operating the swivel-shuttle rail.

2. In a loom of the class described, a lay a crank-shaft for operating the lay, a swivelshuttle rail and a second crank-shaft for oploose on a stud 2b, which is secured to the loom-frame. Attached tothe gear 25 to rotate therewith is a mutilated gear 27, having teeth 27 on half of its periphery and the other half blank, as shown at 27 In line with the gear 27"is a gear 28, fast on the The gear 28 has a dwell portion 28 thereon, (see Fig. 2,) Whichin the revolution of said gear through the revolution of the gear 27 will engage with and travel on the blank space 27" on the gear 27 during a half-rotation of said gear 27, leaving the gear 28 at rest and also the crankshaft 15, as will be well understood by those skilled in the art. Any other suitable mechanism for communicating an intermittent rotation to the crank-shaft 15 at regular intervals and through crank-connectors 1 1 to the rods 9 and swivel-shuttle rail 18 may be'used.

In this instance the crank-shaft 7 rotates every pick of the loom and the crank-shaft 15 rotates only every other pick of the loom. The movement of the crank-shaft 15 may be crating the swivel-shuttle rail, and means for operating said crank-shafts.

3. In a swivel-shuttle loom, the combination with aswivel-shuttle rail carrying swivelshuttles, and supported and operated independently of the lay, of a crank-shaft, and

connections therefrom to the swivel-shuttle rail, to operate the same.

a. In aswivel-shuttle loom, a swivel-sh uttle rail, a crank-shaft for operating theswivel shuttle rail, and connections from said crankshaft ,to said rail, to operate the same inde-' pendently of the lay.

5. A swivel-shuttle rail, having swivelshuttles extending in a horizontal plane on its .front side, and also on its rear side, and. the

swivel shuttles having guide eyes for the thread at their inner ends.
